About

Likes are not subscribers. Subshack shows which of your Substack Notes and posts actually bring people in, counted in people rather than percentages, and audits any profile out of 100. Audience and Opportunities show the readers worth answering; Campaigns and welcome messages reach them on your terms — nothing is sent until you press start. Free on Chrome and Firefox.
